TEXTILE FABRIC.

Application filed May 27,

Liquid viscose (cellulose sulphocarbonate or thiocarbonate) may be coagulated or precipitated to form a gelatinous semi-solid impure cellulose hydrate complex by progressivel y projecting a stream of such viscose into a heated atmosphere or into an aqueous solution containing a suitable acid, for instance, sulphuric or hydrochloric acid, or containing and acid salt such as sodium bisulphite or ammonium chloride, eitherwith or without neutral salts or dehydrators, or both.

All such viscose products are amorphous andprimarily so soft and impressionable that they may be marred by handling and must be dehydrated and desiccated to render themfirm enough in texture for commercial use. Ordinarily, elimination of surplus moisture from filaments thus formed is effected by exposing them to airv either at, or above, atmospheric temperature, while wound upon reels, and it is characteristic of fila ments thus produced that they are only capable of an average of eighteen percent, elon- F gation without fracture.

It is the object and effect of my invention to provide a primarily plane web fabric formed of filaments of abnormal capacity for elongation without fracture and consequently susceptible of being embossed or otherwise deformed to form hollow articles such as hat crowns.

In my Letters Patent of the United States, i

No. 1,651,404 granted December 6, 1927 I describe a preferred method and means for producing filaments having such capacity for abnormal elongation; the essential fea tures of the process of manufacture of such filaments being that they are dehydrated by subjection to an alcoholic environment and while supported in such manner that the filaments are not stretched during their. shrinkage which is incident to their desiccation.

However, although I prefer to employ such filaments in the production of my improved fabric; it may be made of filaments formed from ordinary normal viscose. It is usual to employ, in the millinery trade, viscose filaments of such size as to imitate ordinary horse hair and which are inter-' woven to form an elastic resilient fabric, wherein the warp and weft threads are free to slip upon each other at their intersections. However, my improved fabric is of an entirely different character, in that the warp 1926. Serial N0. 112,139.

and weft elements thereof are interlocked at their intersections to prevent their slipping and are preferably of massive size, for instance, one thousand denier, which is approximately .015 of an inch in diameter; such filaments being normally uniformly cylindrical and presenting a durable lustrous surface both before and after their embodiment in the fabric.

As hereinafter described; such filaments are preferably interlocked in rectangular reticulated spaced relation, forming open meshes at least as large as the width-of the filaments. However, whether assembled in such open relation or closely woven; my improved fabric is characterized by the fact that it is capable of being deformed without fracture and substantially without offering any resilient resistance to deformation. Consequently, a hat crown or other millinery device may be bent to any desired shape which it will retain until bent in some other form, by stresses greater than those to which it would normally be subjected by ordinary wear. 7

My invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

In said drawings; Fig. I is a diagrammatic transverse sectional View of a hat crown, which is a typical hollow article which may be formed from a primarily plane fabric embodying my invention.

Fig. II is a plan view of a fragment of the preferred form of my improved fabric.

Fig. III is a transverse sectional view of iziid fabric, taken on the line III, III in Fig.

In Fig. I; the normally plane fabric indicated by the line 1 is embossed to form the concavo-convex hat crown 2 having the reversely eonvexed brim 3. However, it is to be understood that such primarily plane fabric 1 may be bent or otherwise deformed to any desired shape without fracture, providing that it is not thereby elongated more than one hundred percent, from its original form.

As indicated in Fig. II; said fabric 1 is preferably formed of two series of viscose filaments, respectively parallel warp filaments 5 and parallel weft filaments 6 dis posed in transverse, rectangular, reticulated, spaced relation in the primarily plane web 1. Each of said filaments 5 and 6 having capacity for abnormal elongation and inelastic deformation, are interlocked at their bossing of the fabric; for instance, to the concavo-convex form indicated at 2 in Figs. I and III.

However, I do not desire to limit myself to the precise detailsof construction and arrangement herein set forth,'as it is obvious that various modifications may bev made therein, without departing from the essential features of my invention, as defined in the appended claims.

I claim:

1. A textile fabric, comprising two series of similar viscose filaments, in spaced decussated relation, in a primarily plane webi; said filaments having capacity for abnormal elongation and inelastic deformation without fracture, and being individually, intrinsically, permanently corrugated in interlocked relation at their intersections.

2. A textile fabric, comprising two series of normally cylindrical viscose filaments, in transverse, reticulated, spaced relation; all of said filaments being of the same compo sition and character and having capacity for abnormal elongation and deformation without fracture, and being individually, intrinsically, permanently corrugated and locally flattened in interlocked relation at their intersections.

3. A textile fabric, comprising two series of normally cylindrical viscose filaments, in spaced decussated relation; all of said filaments being of the same composition and character and having capacity for abnormal elongation and inelastic deformation and being individually,intrinsically, permanently corrugated and locally flattened in interlocked relation at their intersections.

4. A textile fabric, comprising two series ofnormally cylindrical viscose filaments, in spaced decussated relation; all of said filaments being of the same composition and character and having capacity for abnormal elongation and inelastic deformation without fracture, and being individually, intrinsically, permanently corrugated and locally flattened in interlocked relation at their intersections.

5. A textile fabric, comprisin two series of normally cylindrical viscose filaments, of the same degree of softness and arranged in rectangular spaced decussated relation,

rugated and locally flattened in interlocked relation at their intersections; whereby said web 1s retamed 1n concavo-con'vex form.

6. A textile fabric, comprlsmg two series of normally cylindrical viscose filaments, in

rectangular spaced decussated relation, in a primarily plane web; said filaments having equal capacity for abnormal elongation and inelastic deformation and being individually, intrinsically, permanently corrugated and locally flattened in interlocked relation at their intersections; regions of said web being embossed from its normal plane; whereby said filaments are retained in embossed relation.

7; A textile fabric, comprising two series of normally cylindrical viscose filaments, in rectangular spaced decussated relation, in a primarily plane web; said filamentshaving capacity for abnormal elongation and inelastic deformation and being individually, intrinsically, permanently corrugated and locally flattened in interlocked relation at their intersections; said web being embossed I to form a hollow article; whereby said filaments are prevented from. resuming their primarily plane relation.

8. A textile fabric, comprising two series of normally cylindrical, massive, viscose filaments, in rectangular spaced decussated relation, in a primarily'plane web; said filaments having capacit ',':for abnormal elongation and inelastic ormation and being individually, intrinsically, permanently corrugated and locally" flattened in interlocked relation at their intersections; said web being embossed to concavo-convex shape, to form a hollow article; whereby said filaments are retained in such embossed relation.

9. A textile fabric, comprising two series of viscose filaments, of the same diameter, in

rectangular spaced decussated relation; all
